Faulty Memory Dimms - Sun Microsystems Sun Fire V60x Manual

Faulty Memory DIMMs

Note – This note applies if you are using BIOS release 5.0 (v1175) or later.
If you don't add, remove or replace any memory DIMM modules and you encounter
memory errors during POST after issuing a soft reset, hard reset or powering on the
system, then the BIOS is detecting faulty memory DIMM modules in the system
during memory test in POST.
The BIOS will log an error in the System Event log, disable the memory bank that
contains the faulty memory DIMM modules and reset the system. Upon rebooting,
the system will either appear to have no memory installed or will boot with one of
the memory banks disabled.
If this occurs, perform one of the following procedures to reset the system after
replacing the faulty memory DIMM modules. Choose the procedure that
corresponds with how many DIMMs are in your system.

2. Boot the system with the Diagnostics CD in the CD-ROM drive to enter the
Diagnostic CD menu or press the F4 key at the initial bootup screen to enter the
